Nokia Siemens has implemented what it says is "a bundle of standards-based features that improve smartphone performance on HSPA+ network, known as Continuous Packet Connectivity (CPC)."
According to Nokia Siemens, "By reducing network interference the feature set provides five times more uplink capacity and allows operators to support more smartphone users on HSPA+ networks. In addition, smart device batteries last 15 percent longer while people benefit from a 60 percent increase in data rates."
It says the tests were conducted in its laboratory using its Flexi Multiradio Base Station with commercial HSPA+ software and Nokia smartphones, in collaboration with experts from a tier-1 telco.
And progress on implement CPC appears to be slow. In February 2010 Nokia Siemens announced that it had successfully conducted the world's first call using CPC, saying "CPC can mean up to 100 percent longer battery life when devices are used for data applications, and up to 50 percent during voice calls." The company said then that the Flexi base station and radio network controller "can support the CPC feature with a simple software upgrade."
Commenting on the latest test results, Timo Joutsenvirta from smart devices technology marketing at Nokia Siemens Networks' 50 percent shareholder, Nokia, said: "The results prove that this technology is effective in increasing data speeds and improving user experience especially when sharing pictures and files in social media and other services. This technology also has a positive impact on battery life. We are looking to adapt CPC to our smart devices platforms to maximize the benefits it delivers." However he gave no timeframe.
